AO6: Candidates must use a range of vocabulary and sentence structures for…

The idea

AO6 rewards deliberate language control rather than simply using long words. In a storm description, swap repeated phrases like "very big" for precise adjectives such as "vast", "towering" or "immense", and vary sentence structures. You might place a short simple sentence ("Thunder cracked overhead.") beside a complex one ("As the rain hammered the roof, the family huddled indoors.") to build tension. Match choices to purpose: persuade with rhetorical questions; inform with precise nouns. Check the spelling of ambitious words and punctuate for effect, using commas, semicolons, colons and dashes accurately. Proofread carefully for sentence boundaries, apostrophes and capital letters to ensure technical accuracy supports your meaning.

What earns the marks

• Vocabulary is chosen for precision and effect, not merely rarity: "the wind clawed at the shutters" beats "the wind was very bad".
• Sentence structures are varied deliberately: simple, compound and complex forms, varied openings, and controlled lengths that mirror tension or calm.
• Clarity is preserved: ambitious wording and complex syntax never obscure meaning for the reader.
• Purpose and effect are evident: language choices suit description, narration, persuasion or explanation as the task demands.
• Spelling of common and ambitious vocabulary is accurate, including irregular forms and homophones.
• Punctuation is accurate and used for effect: full stops, commas, apostrophes, speech punctuation, semicolons, colons and dashes.
• Technical accuracy supports communication: sentence demarcation, tense consistency and subject-verb agreement are secure.

Common mistakes and how to put them right

• Padding with long, misused words.

  Put it right: Choose words whose meaning and register you can control, then check them in a dictionary.

• Monotonous sentence openings: every sentence begins with "The" or "I".

  Put it right: Reorder clauses, begin with adverbs, prepositional phrases or verbs where effective.

• Punctuation used decoratively: commas or exclamation marks scattered without grammatical purpose.

  Put it right: Learn each mark's job and apply it only where the sentence requires it.

Exam tips

• Plan two or three deliberate vocabulary choices and one structural contrast before writing, then deploy them naturally.
• Leave three minutes to proofread for apostrophes, sentence boundaries and the spellings you personally find tricky.
• Read your work aloud in your head: if you stumble, the punctuation or syntax probably needs adjusting.
